Ablation studies on paired models Pix2Pix and TURBO on locally synchronized data. All results are obtained on Galaxy Cluster SMACS 0723. The label “TURBO same D” corresponds to an approach, when the same discriminator is used for generated and reconstructed Webb and Hubble images. The label “LPIPS” denotes adding perceptual similarity loss.
